now i have a problem: i want to run a simulation, high speed(0.3Ma)gas flow over the surface of powder bed(d=6&mu;m).I am a beginner of CFX, and didn't known which software can solve my question? thanks!

In fact, i want to devise a machinery which can fluidize metal powder, and i want the flux can be control by the speed of flow. The high speed wind which may be supersonic blow over the surface of powder bed. And have the question what i expound above.
